Abstract
A method for increasing data throughput on a wireless local area network in the presence of intermittent interference. The method of one embodiment comprises receiving a data packet through a wireless channel. Quality of the wireless channel is evaluated. A packet error ratio (PER) value is calculated for the data packet. The PER value is checked as to whether it is within an acceptable level. A determination is made as to whether an intermittent noise is affecting the PER value.
Claims25
A method comprising:
- receiving a data packet through a wireless channel;
- evaluating quality of said wireless channel;
- calculating a packet error ratio (PER) value for said data packet;
- checking whether said PER value is within an acceptable level;
- and
- determining whether an intermittent noise is affecting said PER value.
A method comprising:
- evaluating a data packet for any error;
- checking whether said data packet includes a packet error;
- calculating a packet error ratio (PER) for said data packet;
- and
- raising data rate setting at which subsequent data packet are transmitted if no packet error exists and said PER is less than a raise rate threshold.
An apparatus comprising:
- a wireless transceiver to send and receive a data packet via wireless communications;
- a network interface card coupled to said wireless transceiver, said network interface card to connect to another wireless device to form a wireless local area network;
- and
- firmware comprising control logic to calculate a packet error ratio (PER) value for said data packet, check whether said PER value is within an acceptable level, determine whether an intermittent noise is affecting said PER value, step up data transfer rate at which said data packet is transmitted if said PER value is less than a raise rate threshold and said intermittent noise is due to a frequency hopping spread spectrum (FHSS) device.
A machine readable medium having embodied thereon a computer program, said computer program being executable by a machine to perform a method comprising:
- calculating a packet error ratio (PER) value for said data packet;
- checking whether said PER value is within an acceptable level;
- determining whether an intermittent noise is affecting said PER value;
- determining whether said intermittent noise is due to a frequency hopping spread spectrum (FHSS) wireless device;
- and
- stepping up a bit rate at which said data packet is transmitted if said PER value is less than a raise rate threshold.
